The documentation that comes with Glibc recommends to build the package not in the source directory but in a separate, dedicated directory: mkdir ../glibc-build cd ../glibc-build Next, prepare Glibc to be compiled: ../glibc-&glibc-version;/configure --prefix=/usr \     --disable-profile --enable-add-ons \     --libexecdir=/usr/bin --with-headers=/usr/include The meaning of the configure options are: --disable-profile: This disables the building of the libraries with profiling information. Omit this option if you plan to do profiling. --enable-add-ons: This enables any add-ons that we installed with Glibc, in our case Linuxthreads. --libexecdir=/usr/bin: This will cause the pt_chown program to be installed in the /usr/bin directory. Continue with compiling the package: make We'll continue with installing the package. The Linuxthreads man pages are not going to be installed at this point because it requires a working Perl installation. We'll install Perl later on in this chapter, and the man pages will be installed when Glibc is installed for the second time at the end of this chapter. make check make install The locales (used by Glibc to make your Linux system talk in a different language) weren't installed when you ran the previous command, so we have to do that ourselves now: make localedata/install-locales An alternative to running the previous command is to install only those locales which you need or want. This can be achieved using the localedef command. Information on this can be found in the INSTALL file in the glibc-&glibc-version; tree. Build the linuxthreads man pages: make -C ../glibc-2.3.2/linuxthreads/man Install the man pages: make -C ../glibc-2.3.2/linuxthreads/man install
